ARRANGEMENT FOR AND METHOD OF PROJECTING AN IMAGE WITH SAFETY CIRCUITRY |
摘要 |
Red, blue and green lasers respectively emit a plurality of red, blue and green laser beams having respective output powers. The beams are optically focused and collinearly arranged to form a composite beam which is swept by a pair of scan mirrors in a pattern of scan lines on a projection surface, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the composite beam to produce an image. A safety circuit detects a malfunction of at least one of the lasers and the scan mirrors, and deenergizes the at least one of the lasers and the scan mirrors upon detection of the malfunction. |
